Reduced physiological performance and cellular tolerance of gene silenced maize plants to drought stress. Five plants at 14 dpi were subjected to drought stress and stress response was measured on fifth day. Photosynthesis rate (a), Efficiency of PSII in light adapted leaves (b), and Instantaneous water use efficiency (WUEi) (c) were measured using portable photosynthesis system. Cell membrane stability (d) and Osmolality (e) were measured from the leaf tissue. Cell membrane damage was calculated as per cent injury. BMV-inoculated plants were used as reference for statistical analysis. The values are means ± SE (n = 5). * and ** indicate significant difference from BMV-inoculated plants at P ≤ 0.05 and P ≤ 0.01, respectively. WT, non-inoculated; BMV, vector inoculated; all others with BMV:: followed by gene name are respective gene-silenced plants.
